• [x] This change requires a documentation update

How has this been tested?

• Tested against AD7944, AD7986 and AD7985 eval boards attached to a zedboard.

• Generalized manual test flow:

install pyadi-iio and dependencies in venv Start Python interpreter import adi Instantiate adc object, e.g. adc = adi.ad7944(uri="ip:10.2.5.203") Check that adc.rx() succeeds with no warnings or errors Check sampling frequency with adc.sampling_frequency Set sampling frequency with adc.sampling_frequency = Check sampling frequency again with adc.sampling_frequency and confirm change successful

• Test artifacts for pytest-libiio added as test/test_ad7944.py and run from local machine using e.g.: pytest --hw=ad7944 -v test/test_ad7944.py --uri=ip:10.2.5.203 and pytest -v --emu --emu-xml=ad7944.xml test/test_ad7944.py
